ABSTRACT:
An electronic-breathing mask system uses an electro-pneumatic valve for controlling air flow to a pilot. The system provides a continuous flow of air in an amount proportional to the pressure in the mask. The pressure in the mask is compared against a setpoint pressure to maintain a minimum derived pressure therein.
